8AN Cap

The anodized matte black finish matches my other fittings perfectly, and the threads engaged smoothly without any cross-threading. It seals tightly with just hand-tightening, so no leaks on the first try. Exactly what I needed to close off my fuel rail.

Finally got around to capping off my unused fuel rail port and this 8AN cap threaded on smooth without any binding. The flare seat sealed up tight on the first try with no leaks.

The matte black anodized finish matches my other fittings perfectly and the threading is clean, so it screws on smoothly every time. It’s a simple cap, but it does exactly what it’s supposed to on my spare 8AN port. So far it hasn’t leaked a drop.
